In addition, the embodiments and the features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
FIG. 1 is a flowchart of a method of privacy protection of a quotation file according to an exemplary embodiment of the present application.
As shown in fig. 1, the present application proposes a method for privacy protection of an offer file, which may include: step S1, encrypting the file content and the address content of the storage address of the quotation file by using the public key, and setting the decryption time; step S2, after the decryption time is reached, starting a private key to obtain a storage path of a bid item corresponding to the quotation file, and assigning the storage path of the bid item to a storage address; and step S3, calling a storage path, acquiring a quotation file, and acquiring the file content by using a private key.
In some embodiments, in order to improve the security of the bid data of the bidder, the bid file of the bidder is first double-encrypted with the file content and the address content of the storage address, and a decryption time is set, wherein the decryption time can be set according to the bid progress, which is not limited herein.
In some embodiments, the quotation file is stored on a server; and the storage address is stored in the database after the encryption of the address content. Because the database authority and the server authority are separated, fewer people can have the two authorities at the same time, and the security performance of the quotation file is improved.
In some embodiments, the storage address is a fixed position, after the address content of the storage address is encrypted, the address content in the storage address is cleared, that is, the built-in content in the storage address is blank, so that the defect that the storage address is easy to crack in the prior art is overcome.
In some embodiments, the private key is obtained when the decryption time is reached; starting a private key to trigger the project code of the bid item corresponding to the quotation file; and searching a storage path of the bid item through the item code, and assigning the storage path to a storage address. Specifically, each bid item has a unique item code, and the item code of the bid item is triggered after a public key and a private key are acquired for the bid item corresponding to the quote file; further, an address corresponding to the bid item, namely a storage path, is searched through the item code, and the storage path of the bid item is assigned to the storage address as dynamic address content. In other words, after the private key is started, the dynamic address content (i.e., the memory path) will overwrite the blank address content of the memory address, such that there is valid address content in the memory address.
In some embodiments, the memory address is called and the quotation file is found. Further, since the contents of the quotation file are still in an encrypted state at this time, the contents of the file are decrypted by using the private key to obtain the contents of the file.
In some embodiments, the file content is transmitted to the backend server using an application programming interface. It can be understood that a plurality of bidders will obtain a plurality of quotation files, and finally the background server analyzes and calculates the file contents of the plurality of quotation files respectively to obtain the quotation file that can maximize the interest of the bidders, i.e. obtain the quotation result.
According to the method for protecting the privacy of the quotation file, the secrecy performance of the quotation data of a bidder is improved by carrying out double encryption on the storage path and the content of the quotation file; in addition, the address content in the storage address is a dynamic address, and is assigned after decryption, so that the defect that the storage address is easy to crack in the prior art is overcome, and the use experience of a user is improved.
FIG. 2 is a block diagram of a system for privacy protection of an offer file according to an example embodiment of the present application.
As shown in fig. 2, the present application also proposes a system for privacy protection of an offer file, which may include: an encryption module 1, an address decryption module 2 and a content decryption module 3. The encryption module 1 is used for encrypting the file content and the address content of the storage address of the quotation file by using the public key and setting the decryption time. The address decryption module 2 is used for starting the private key to obtain the storage path of the bid item corresponding to the quotation file after the decryption time is reached, and assigning the storage path of the bid item to the storage address. The content decryption module 3 is used for calling the storage path, obtaining the quotation file and obtaining the file content by using the private key.
In some embodiments, the address content of the encrypted storage address is blank.
In some embodiments, the step of executing the address decryption module 2 may include: after the decryption time is reached, obtaining a private key; starting the private key to trigger the item code of the bid item corresponding to the quotation file; and searching a storage path of the bid item through the item code, and assigning the storage path to a storage address.
In some embodiments, the public key is automatically activated upon reaching the decryption time and the private key is provided to the tenderer of the bid item.
In some embodiments, the bid item has a unique item code to determine the address of the bid item.
In some embodiments, further comprising: and the background server 4 is used for receiving the file content transmitted by the application programming interface, analyzing and calculating the file content and acquiring a bidding result aiming at the bidding item.
According to the system for protecting the privacy of the quotation file, the secrecy performance of the quotation data of a bidder is improved by carrying out double encryption on the address and the content of the quotation file; in addition, the address content in the storage address is a dynamic address, and is assigned after decryption, so that the defect that the storage address is easy to crack in the prior art is overcome, and the use experience of a user is further improved.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
